# clio
clio is an XRP Ledger RPC server. clio is optimized for RPC calls. Validated
historical ledger and transaction data is stored in a more space efficient format,
using up to 4 times less space than rippled.
using up to 4 times less space than rippled. clio stores data in either Postgres
or Cassandra, allowing for scalable read throughput. Multiple clio nodes can share
access to the same dataset, allowing for a highly available cluster of clio nodes,
without the need for redundant data storage or computation.
clio offers the full rippled API (this is still in development at the time of writing),
with the caveat that clio by default only returns validated data.
clio offers the full rippled API, with the caveat that clio by default only returns validated data.
This means that `ledger_index` defaults to `validated` instead of `current` for all requests.
Other non-validated data is also not returned, such as information about queued transactions.
For requests that require access to the p2p network, such as `fee` or `submit`, clio automatically forwards the request to a rippled node, and propagates the response back to the client. To access non-validated data for *any* request, simply add `ledger_index: "current"` to the request, and clio will forward the request to rippled.
